Corolla Verso D-CAT 177 PS stinks to the sky – new VERSO from May 2009?

Hello dear forum, First question: Our meanwhile almost 3 years old D-CAT (about 60 TKM on it) stinks for about 4 months every few days extremely unpleasant after biting exhaust gases – both in the interior and from outside. Often then a strong smoke development from the end pot can be perceived – but not always. We were already twice at TOYOTA in Frankfurt – there you could not find anything – it is to get crazy. The neighbors laugh already (nothing with “Clean Power” and we also find it Of course I used the SUCHFUNKTION in the forum and therefore tap on a defective soot particle filter – what else could it be??? Has someone had similar experiences? The Crux is that the car sometimes doesn’t stink for 2-3 days, then extreme again. By the way, we drive a lot of short distance in urban traffic. Second question: is it true that a new COROLLA Verso should come out in Germany from May 2009? Thanks in advance for your suggestions and tips. S tefan
